如何終止用戶並更新當前剩餘用戶的標籤？

Question

我已創建成員並將它們存儲到數據庫中。我有一個數據庫中存儲的所有用戶的標籤，每次保存的數字都會增加。我也有一個終止按鈕，終止於保單號碼，所以這就是我想要的。當您終止成員時，它也必須從標籤更新當前成員。例如，總會員數= 10，當您終止用戶時，總會員標籤也必須更新到9.我該怎麼辦？

這是我迄今所做..

1. 總加載成員

   protected void Page_Load(object sender, EventArgs e) 
   { 
       lblTotal.Text = "Total Members Captured : " + CountMembersCaptured(); 
   } 
   

2. 總會員

   protected int CountMembersCaptured() 
   { 
       List<SP_COUNTPOLICYMEMBERSResult> _MemberCountList = _dc.SP_COUNTPOLICYMEMBERS().ToList(); 
       return _MemberCountList.Count(); 
   } 
   

3. 程序法獲得總會員

   ALTER PROCEDURE [dbo].[SP_COUNTPOLICYMEMBERS] 
       AS 
       BEGIN   
       SELECT [DateID] 
       ,[PolicyNumber] 
       ,[Name] 
       ,[PolicyName] 
       ,[InceptionDate] 
       ,[Active] 
       FROM [dbo].[tblPolicy] 
       END 
   

4. 終止鍵

   protected void btnTerminate_Click(object sender, EventArgs e) 
   { 
   
       if (Session["DateID"] != null) 
       { 
        List<tblPolicy> _PolicyMemberList = _dc.tblPolicies.Where(a => a.DateID == int.Parse(Session["DateID"].ToString())).ToList(); 
   
        if (_PolicyMemberList != null) 
        { 
         if (_PolicyMemberList.Count() > 0) 
         { 
          foreach (tblPolicy _PolicyMember in _PolicyMemberList) 
          { 
           _PolicyMember.Active = false; 
          } 
   
          _dc.SubmitChanges(); 
          lblresults.Text = "Confirmation: Member has been terminated/deleted successfully.!"; 
         } 
        } 
       } 
   } 
   

Answer 1

添加Where子句中的SELECT查詢。

ALTER PROCEDURE [dbo].[SP_COUNTPOLICYMEMBERS] 
    AS 
    BEGIN   
    SELECT [DateID] 
    ,[PolicyNumber] 
    ,[Name] 
    ,[PolicyName] 
    ,[InceptionDate] 
    ,[Active] 
    FROM [dbo].[tblPolicy] where Active=1 
    END 

希望這有助於...

ALTER PROCEDURE [dbo].[SP_COUNTPOLICYMEMBERS] 
AS 
BEGIN   
SELECT [DateID] 
,[PolicyNumber] 
,[Name] 
,[PolicyName] 
,[InceptionDate] 
,[Active] 
FROM [dbo].[tblPolicy] WHERE [Active]=1 
END 

protected void btnTerminate_Click(object sender, EventArgs e) 
{ 

if (Session["DateID"] != null) 
{ 
    List<tblPolicy> _PolicyMemberList = _dc.tblPolicies.Where(a => a.DateID == int.Parse(Session["DateID"].ToString())).ToList(); 

    if (_PolicyMemberList != null) 
    { 
     if (_PolicyMemberList.Count() > 0) 
     { 
      foreach (tblPolicy _PolicyMember in _PolicyMemberList) 
      { 
       _PolicyMember.Active = false; 
      } 

      _dc.SubmitChanges(); 
      lblresults.Text = "Confirmation: Member has been terminated/deleted successfully.!"; 
      lblTotal.Text = "Total Members Captured : " + CountMembersCaptured(); 
     } 
    } 
} 
}
